Ingredients:

• 1½ pounds (680g) ground chuck (80/20 blend) 
• 1 tablespoon Worcestershire sauce 
• 1 teaspoon garlic powder 
• 1 teaspoon onion powder 
• Salt and freshly ground black pepper, to taste 
• 4 brioche burger buns, toasted 
• 4 slices aged cheddar cheese 
• 4 tablespoons caramelized onions 
• Arugula 
• 8 slices cooked bacon 
• 4 tablespoons aioli or truffle mayo

Instructions:

1. In a bowl, combine ground chuck, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Form into 4 patties. 
2. Preheat grill to medium-high. Grill patties about 4 minutes on one side. Flip, add cheese, and cook until desired doneness, about 3 more minutes for medium-rare. 
3. On the bottom half of each toasted brioche bun, place a layer of arugula, followed by the grilled patty with cheese, caramelized onions, two slices of bacon, and a dollop of aioli or truffle mayo. Add any optional toppings like sautéed mushrooms or avocado slices if desired. 
4. Cap with the top half of the brioche bun. Serve immediately with a side of sweet potato fries or a mixed green salad for a complete gourmet experience
